Abstract

Abstract Die Knoevenagel‐Reaktion der Enolformen (I) der entsprechenden Benzoylpyrrolidintrione mit Malononitril führt zu den Pyrrolopyridintrionen (II), während die Enamine (IVa) und (IVb) in siedendem Toluol in Gegenwart von Essigsäure mit Malononitril die Verbindungen (V) bilden (die isomeren E‐Formen geben diese Reaktion nicht).
